NVIDIA GeForce GTX 650 Ti Boost vs NVIDIA Quadro P4000 Comparison

Head-to-Head Benchmarks

The recorded data shows a decisive performance gap between the NVIDIA Quadro P4000 and the NVIDIA GeForce GTX 650 Ti Boost in the two shared benchmark tests. In Geekbench OpenCL, the Quadro P4000 scores 36,212 compared to 9,302 for the GTX 650 Ti Boost, a delta of 289.3%. In Geekbench Vulkan, the Quadro P4000 reaches 41,786 while the GTX 650 Ti Boost manages 10,041, a delta of 316.2%. These are not marginal differences; the Quadro P4000 outperforms the GTX 650 Ti Boost by nearly threefold in OpenCL and over threefold in Vulkan.

The head-to-head results show the Quadro P4000 winning both tests, with 2 wins and 0 losses. The OpenCL gap is particularly telling: the Quadro P4000's score of 36,212 is over 3.8 times the GTX 650 Ti Boost's 9,302. For Vulkan, the ratio is even steeper: 41,786 versus 10,041, meaning the Quadro P4000 delivers roughly 4.2 times the performance in that API. These deltas reflect not just architectural maturity but also the massive difference in shading resources and memory configuration between the two cards.

When placed against their respective nearest rivals in the database, both cards sit in a similar percentile range. The Quadro P4000 holds a 47th percentile ranking among all GPUs, while the GTX 650 Ti Boost sits at the 42nd percentile. Their average benchmark scores are 9,665 and 8,067 respectively. The Quadro P4000's nearest rival is the AMD Radeon Pro WX 2100, which averages 9,653, a delta of only 0.1%. The GTX 650 Ti Boost's nearest rival is the NVIDIA GRID K2 at 8,080, a delta of -0.2%. Despite the massive head-to-head advantage, neither card is an outlier in its own performance tier; the Quadro P4000 is merely 0.2% above the GeForce GTX 960M and 0.3% above the Quadro K5000, while the GTX 650 Ti Boost is 0.2% above the GTX 650 Ti and 0.3% above both the GTX 880M and Quadro P5000.

The benchmark data indicates that the Quadro P4000's dominance over the GTX 650 Ti Boost is not a close contest. The smallest margin, 289.3% in OpenCL, still represents a multi-generational leap. The largest margin, 316.2% in Vulkan, suggests that the Quadro P4000 benefits from better driver optimization and hardware support for modern graphics APIs. The GTX 650 Ti Boost, with its older Kepler architecture and DirectX 12 (11_0) support, cannot match the Pascal-based Quadro P4000's DirectX 12 (12_1) feature set in these compute-oriented workloads.

Architecture Differences

The two cards come from entirely different architectural generations. The Quadro P4000 uses the GP104 chip built on the Pascal architecture, manufactured on a 16 nm process at TSMC. The GTX 650 Ti Boost uses the GK106 chip from the Kepler architecture, manufactured on a 28 nm process, also at TSMC. The process node difference alone explains much of the performance gap: 16 nm versus 28 nm allows the Quadro P4000 to pack 7,200 million transistors into a 314 mm² die, while the GTX 650 Ti Boost fits 2,540 million transistors into a 221 mm² die. The transistor density reflects this: the Quadro P4000 reaches 22.9M transistors per mm², while the GTX 650 Ti Boost manages only 11.5M per mm².

The shading resources differ dramatically. The Quadro P4000 has 1,792 shading units, 112 texture mapping units, and 64 ROPs. The GTX 650 Ti Boost has 768 shading units, 64 TMUs, and 24 ROPs. This means the Quadro P4000 has more than twice the shader count, nearly double the texture units, and over 2.6 times the ROPs. The pixel rate and texture rate reflect these counts: the Quadro P4000 achieves 94.72 GPixel/s and 165.8 GTexel/s, while the GTX 650 Ti Boost achieves 16.51 GPixel/s and 66.05 GTexel/s. The FP32 performance is similarly lopsided: 5.304 TFLOPS for the Quadro P4000 versus 1.585 TFLOPS for the GTX 650 Ti Boost.

Memory configuration is another point of divergence. The Quadro P4000 carries 8 GB of GDDR5 on a 256-bit bus, yielding 243.3 GB/s of bandwidth. The GTX 650 Ti Boost has 2 GB of GDDR5 on a 192-bit bus, yielding 144.2 GB/s. The Quadro P4000 also runs its memory at 1901 MHz (7.6 Gbps effective), while the GTX 650 Ti Boost runs at 1502 MHz (6 Gbps effective). Both cards use a PCIe 3.0 x16 interface, but the Quadro P4000's larger memory pool and wider bus give it a clear advantage in bandwidth-hungry workloads. The GTX 650 Ti Boost's smaller 2 GB frame buffer may limit it in modern applications that require more than 2 GB of VRAM.

Clock speeds also favor the Quadro P4000. Its base clock is 1202 MHz with a boost of 1480 MHz, compared to 980 MHz base and 1032 MHz boost for the GTX 650 Ti Boost. The Quadro P4000 also supports FP16 at 82.88 GFLOPS with a 1:64 ratio, while the GTX 650 Ti Boost has no FP16 data recorded. In terms of API support, the Quadro P4000 runs DirectX 12 (12_1), OpenGL 4.6, and Vulkan 1.4. The GTX 650 Ti Boost supports DirectX 12 (11_0), OpenGL 4.6, and Vulkan 1.2.175. The higher DirectX feature level and newer Vulkan version give the Quadro P4000 better compatibility with current and future titles.

Where Each One Wins

The Quadro P4000 wins decisively in every recorded benchmark category shared with the GTX 650 Ti Boost. In Geekbench OpenCL, the Quadro P4000's 36,212 score dwarfs the GTX 650 Ti Boost's 9,302. This test measures general-purpose compute performance across a variety of workloads, including physics, encryption, and image processing. The Quadro P4000's higher shader count and memory bandwidth make it the clear choice for OpenCL-based applications such as video encoding, scientific simulation, and data processing. The GTX 650 Ti Boost, with 768 shading units and 144.2 GB/s bandwidth, simply lacks the resources to compete in these scenarios.

In Geekbench Vulkan, the Quadro P4000 scores 41,786 versus 10,041 for the GTX 650 Ti Boost. Vulkan is a low-overhead graphics and compute API, and the Quadro P4000's newer Pascal architecture, with its improved command processor and memory management, delivers over four times the performance. This makes the Quadro P4000 better suited for modern games and applications that leverage Vulkan's explicit control over GPU resources. The GTX 650 Ti Boost, with its older Kepler design and Vulkan 1.2.175 support, cannot keep pace.

Beyond the head-to-head tests, the Quadro P4000's other recorded benchmarks show strengths in specific areas. Its Passmark G3D score of 11,466 and Passmark GPU Compute score of 4,913 indicate strong performance in DirectX 11 and compute workloads. The GTX 650 Ti Boost has no recorded scores for these tests, so a direct comparison is not possible from the database. However, the Quadro P4000's Passmark DirectX 9 score of 181 and DirectX 10 score of 66 suggest it handles legacy APIs well, though these numbers are not directly comparable to the GTX 650 Ti Boost's lack of data.

The GTX 650 Ti Boost's only recorded benchmarks are Geekbench Metal, OpenCL, and Vulkan. Its Metal score of 4,858 is not matched by the Quadro P4000, which has no Metal benchmark in the database. This means the GTX 650 Ti Boost may have an edge in Metal-specific applications, though this is not a head-to-head comparison. On the whole, the data shows the Quadro P4000 winning 2 out of 2 shared tests, with the GTX 650 Ti Boost winning 0. The Quadro P4000 is the superior card for OpenCL and Vulkan workloads, while the GTX 650 Ti Boost's only potential advantage lies in Metal, where no comparative data exists.

The Verdict

The benchmark data is unambiguous: the NVIDIA Quadro P4000 outperforms the NVIDIA GeForce GTX 650 Ti Boost by a wide margin in every shared test. In Geekbench OpenCL, the Quadro P4000 leads by 289.3%, and in Geekbench Vulkan, it leads by 316.2%. These deltas are far beyond what any driver or optimization could close. The architectural gap, from Kepler to Pascal, from 28 nm to 16 nm, and from 768 to 1,792 shading units, is insurmountable for the GTX 650 Ti Boost.

Users needing OpenCL or Vulkan performance should choose the Quadro P4000 without hesitation. Its 5.304 TFLOPS of FP32 compute, 243.3 GB/s of memory bandwidth, and 8 GB of VRAM make it suitable for professional workloads such as CAD, 3D rendering, and scientific computing. The GTX 650 Ti Boost, with 1.585 TFLOPS and 2 GB of VRAM, is better suited for older games or light productivity tasks, but even then, the Quadro P4000's superior specifications will likely deliver better results in any modern application.

The Quadro P4000 also holds a higher percentile ranking, at 47th versus 42nd for the GTX 650 Ti Boost, and a higher average benchmark score of 9,665 versus 8,067. While both cards sit near the middle of the database's performance distribution, the Quadro P4000 is consistently faster. Its nearest rival, the AMD Radeon Pro WX 2100, averages 9,653, only 0.1% behind, indicating that the Quadro P4000 is competitive within its class. The GTX 650 Ti Boost's nearest rival, the NVIDIA GRID K2, averages 8,080, just 0.2% ahead, showing that the GTX 650 Ti Boost is also near the top of its own tier.

For anyone deciding between these two cards, the data points to the Quadro P4000 as the clear winner. Its 2 wins and 0 losses in head-to-head benchmarks, combined with its architectural advantages, make it the superior choice for virtually any use case. The GTX 650 Ti Boost may still be found in older systems, but it cannot compete with the Quadro P4000 on any level measured in this database.
